A vulnerability was found in Netentsec NS-ASG Application Security Gateway 6.3 and classified as critical. Affected by this issue is some unknown functionality of the file /protocol/firewall/uploadfirewall.php. The manipulation of the argument messagecontent leads to sql injection. The exploit has been disclosed to the public and may be used. VDB-243590 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
